Confirming rumors that the Bridesmaids star would say goodbye to the late night laugher when its 37th season wrapped, cast members gave Wiig an emotional sendoff at the end of last night's show, with first-time hostMick Jagger kicking off the musical tribute.

In what looked like a high school graduation skit at first glance, it soon became clear this was something more, when the usually upbeat Wiig started to get a little teary-eyed.

"Well another year has come and gone and I just want to say how proud I am of this graduating class," Jagger said, playing what looked like the principal of the school. "I'd like to take a moment to say goodbye to one particular student who is leaving this summer. You've meant quite a lot to us these seven years…so our music department got together and prepared a song to say goodbye. This one's for you."

Then, Wiig proceeded to take off her graduation gown and dance with the cast members to the Rolling Stones' "She's Like a Rainbow." As she wiped away tears, Amy Poehler and Rachel Dratch also appeared to send off Wiig (and the season), singing along with the group.

While the 38-year-old funnylady has stayed mum about her possible departure from the show this season, she did say last month that it "will be the hardest thing" if she did sign off.

"This is my seventh year and that's my family," Wiig said on Alec Baldwin's podcast Here's the Thing. "It's my heart. It's New York to me…I will say that when I do leave it's not because I'm sick of it and not because I see something better or anything like that. It's just that it's time. When I do leave, it will be the hardest thing...you're there for a week and on Saturday night you're sad because you leave these people. You have to leave things that you love."

But, before the show took an emotional turn, there were many other notable moments on SNL's season finale, most of which came courtesy of Jagger (and one awesome reboot of Lazy Sunday).

The 68-year-old music legend rocked as first-time host of the show, switching up between musical performances with the Foo Fighters (a medley of "19th Nervous Breakdown" and "It's Only Rock'n'Roll"), Arcade Fire ("The Last Time") and Jeff Beck (a new politics-fueled song called "Tea Party") and skits in which Jagger played a variety of characters, including Steven Tyler.

In a skit called "So You Think You Can Dance at an Outdoor Music Festival," Jagger gave a spot-on impression of the Aerosmith frontman, a judge on the show, while Abby Elliott played Jewel, and Fred Armisen played Santana, who struggled to name his songs. Jagger even gave some Tyler-esque howls while he was at it.

And while that was probably the most talked about Jagger skit of the night, Jagger also killed as a shy insurance agent who was too nervous to get up and sing karaoke in front of everyone.

"I could never get up in front of a room full of people like this. I just don't have that kind of confidence," Kevin (Jagger) said. Meanwhile, Kevin's colleagues Fred Armisen and Bobby Moynihan weren't afraid to show off their karaoke chops, taking the stage to perform Jagger's songs (and imitate him), which impressed his other co-workers, Wiig and Vanessa Bayer.

"I seriously feel like I'm in the same room with Mick Jagger," Bayer said of Armisen's performance.

Jagger also was funny in "Secret Word," competing against Wiig's Mindy Elise Grayson in the game show as flamboyant actor Chaz.

After kicking off the show's 100th digital episode on the last show, Andy Samberg brought back "Lazy Sunday," rapping "Lazy Sunday 2" with his compadre (former SNL cast member Chris Parnell), seven years after the duo debuted the original version (the first SNL digital short ever back in 2005).

There were also a couple of cameos on the show, with Steve Martin popping up in full "Californian" garb on "The Californians," and Jon Hammreturning to the show to play an Italian singer who keeps getting harassed by a teensy-handed Kristin Wiig, but eventually falls for the oddball singing sister from Finger Lakes.

So, tell us, what did you think of Jagger's first time hosting stint on SNL?
